Description
cd /usr/mysql-test; ./mtr maria-no-logging
|
(as root) gives me an error report as below. The odd-looking file name starting with a ";" can vary between runs. I am keeping the mysql-test directory, so please let me know if you'd like anything else from it.

A full fix of this is now pushed to 10.0 tree, revision 4422
Sergei will push a small patch to 5.5 to fix this issue in 5.5
I backported from commit https://bazaar.launchpad.net/~maria-captains/maria/10.0/revision/4422 the patch http://anonscm.debian.org/cgit/pkg-mysql/mariadb-10.0.git/tree/debian/patches/fix-maria-no-logging.patch and the test passes now. Thanks!
Not sure this is the right place to report this, but installing third party libraries like mysql-python now fail with:
/usr/include/mysql/my_config.h:654:2: error: #error <my_config.h> MUST be included first!
Reporting it here, since it seems related to this issue. Please advise.
Yes, related.
But as it's a different issue I've reported it separately. MDEV-6862.
I cannot think of a simple workaround, besides removing this #error line from my_config.h
The problem is a in the stat structure at /usr/include/i386-linux-gnu/bits/stat.h
Depending on how you compile your program (with or without __USE_FILE_OFFSET64) the structure gets different sizes.
Here is an example:
#if defined __x86_64__ || !defined __USE_FILE_OFFSET64__off_t st_size; /* Size of file, in bytes. */#else__off64_t st_size; /* Size of file, in bytes. */#endifThe variable is either 4 or 8 bytes, depending on the value of __USE_FILE_OFFSET64,
In storage/maria/ha_maria.cc, we included files in a non standard order and struct stat got to be defined too small, which caused memory overruns.
I have now fixed so that we always include <my_global.h> first, which fixes this issue. I will push this into 10.0 tree shortly
However someone should fix so that 'struct stat' has always the same size, independent of how you compile it on x86.
On 64 bits it's always the same size.
